Designed specifically for RVs, the TF03K is a high-precision battery monitor featuring a 2.8-inch clear display. It simultaneously shows six key parameters—voltage, current, power, capacity, state of charge (SOC), and remaining usable time—eliminating the need for tedious switching between screens. This allows RV users to grasp their battery status instantly, significantly enhancing power management convenience and safety during travels.
Combining robust functionality with intelligence and efficiency, the TF03K supports manual screen brightness adjustment to suit various lighting conditions. When the battery is idle (neither charging nor discharging), it automatically enters a low-power standby mode and turns off the backlight. With an operating power consumption of just 12mA and standby consumption as low as 2mA, it minimizes its own drain on the RV battery.
A standout feature of the TF03K is its 1% measurement accuracy. Even the tiny standby currents from RV appliances are captured and displayed clearly and accurately, addressing blind spots that other monitors might miss—such as undetected power leakage. This precision ensures reliable energy data, giving users full visibility over every watt consumed. Additionally, the built-in customizable low-capacity alarm reminds users when battery levels drop below a preset threshold, effectively preventing damage from over-discharge and adding a critical layer of safety.
To accommodate diverse battery configurations in the RV market, the TF03K is compatible with mainstream battery types—from traditional lead-acid to advanced lithium batteries. It supports an ultra-wide voltage range of 8–120V, covering common RV electrical systems like 12V, 24V, 48V, and 72V. With a current measurement range of 0–750A, it reliably monitors charging and discharging even for high-power appliances onboard.

Battery monitors can be used in any scenario involving battery packs. They continuously track the status of the battery pack and display key parameters such as remaining charge, current voltage, current, power, and other relevant data. This allows users to monitor battery health in real time, helping to protect the battery and extend its lifespan.
It is compatible with mainstream battery types on the market, such as lead-acid batteries, lithium-ion batteries, lithium iron phosphate batteries, sodium batteries, etc.
